Answer:
a. $8211
b. $11,067
Step-by-step explanation:
Depreciation expense using the units-of-production method = miles driven × [(cost of truck - Salvage value)/ total useful life]
Miles driven × [ ($59,500 -$2380) /190,400 miles]
Miles driven × 0.3
Depreciation expense in 2020 = 27,370 × 0.3 = $8211
Depreciation expense in 2021 = 36,890 × 0.3 =$11,067
